Is it possible to make the rug inflammable? So it is possible to make flame retardant with soufa.
I think that it’s basically OK because the felt is sufficiently effective.
Here, the package is used for termite control, but the contents are soufa16% aqueous solution, so it also has a flame retardant effect. If it is such a package, it would be relatively easy to spray it when the incipient nipples are flame-retarded.
It looks like a towel.
The difficulty is the texture after processing.
Because soufa hardens cellulose, I think it is necessary to treat it while adjusting the flame retardancy or to formulate a softener.
